SPECIFICATION forming part of Letters Patent No. 565,723, dated August11, 18196. Application filed March 27,1895- Serial No. 543,333. (Nomodel.)

To all whom t may concern:

Be it known that I, THOMAS` CHALMERs, a citizen of the United States,residing in the city and county of Camden, State of New Jersey, haveinvented a new and useful Improvement in Paper Makers` Gages, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention consists of a paper-makers gage formed of rollers which areadapted to be moved in their bearings by the varying thickness of paperand thereby operate a gage or register and a governor for preventing thetrembling orvibrations of the frame from affecting the vindex-inger ofsaid gage or register. Between the register and rollers is a system oflevers so constructed, ar-

ranged, and combined that the device is simplied, it operatesdelicately, and springs are avoided, excepting such as may exist in theregister, all as will be hereinafter described.

It also consists of the interposition between the governor and thesupport therefor of a knuckle or universal joint, so that said governoris caused to yield when subjected to lateral pressure, thus preventingstrain on the parts.

It also consists in providing the gage or register with a dial havingdifferent sets of graduations thereon relatively to different grades ofpaper to be gaged.

Figure l represents a side elevation of al paper-makers gage embodyingmy invention. Fig. 2 represents a transverse vertical section thereof.Fig. 3 represents a vertical section of the governor and adjacent partson an enlarged scale. Fig. 4 represents a partial side elevation andpartial section of the register. Fig. 5 represents a face view of thedial thereof.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates a vertical frame, and Bdesignates a number of parallel rollers, whose journals are mounted inboxes C, which are loosely tted in the sides of said frame, so as to becapablebf sliding or moving therein. Bearing upon the journal-box orside of the upper roller is a head D, which is pivotally connected withthe horizontal lever E, the latter having one of its ends pivoted to theframe A and the other end pivotally connected with the vertical anddepending rod F, which is attached to one end of the horizontal lever G,:mounted on the frame A parallel or approximately parallel withsaidlever E.

H designates a governor consisting of a cylinder or body containing thepiston J, whose stem K passes freely through stuffing-boxes on the upperand nlower ends of said body, both of said ends being open for thepassage of said piston stem or rod K. The upper end of said stem isattached to the lever G, and

the lower end thereof is attached to the operating mechanism of theregister L, which is secured to the frame A in any suitable manner, andhaving on its dial graduations for indicating the thickness of paper.

` The governor is attached to the frame A by means of the universal orknuckle joint M, whereby the body of the same may yield to any strainthat may be imparted to the stem K due to its connection with the leverG and the register L when said lever is operated.

The rod F is formed in sections connected by the buckle K', whereby thedevice may be adj usted in order to set the hand of the register true tothe proper gage of the paper, and

a uniform relation may be maintained between the levers at all times.

The operation is as follows: A web of paper is passed around therollers, and when the thickness of the saine is normal the index-fingerof the register will remain at the relative graduation. Should, however,the thickness of the paper increase, the rollers will be raised, theeffect of which is the elevation of the head D, and the consequentoperation of the lever G and of the register J, whereby the index of thelatter will indicate said increase, the same being true in reverse orderin the case of a decrease in the thickness, so that under eithercircumstance the paper-maker will be advised that the iiow of pulprequires regulation or adjustment. The register or gage L has its dial Nrotatable on or around the shaft P of the index Q, and is provided withsets of different graduations, as at S, for gaging paper of differentgrades or thickness, so that as the paper is changed the dial will berotated or adjusted so as to bring the proper set of graduations behindthe index Q, the effect of which is evident.

ICO

The governor Il consists of a cylinder with the piston J therein, andthe stem K connected with said piston and having its opposite portionspassing through the ends of the cylinder, as has been stated.

The cylinder is filled With oil or other iiuid in Which the piston J hasits play, and said piston has a port T vertically through the same, sothat the oil or fluid above and below the piston is in communication, itbeing noticed that the oil forms a cushion for the piston or plunger andthus serves to steady the piston in the cylinder Without, however,preventing said piston to be properly raised by the elevation of thelever G, the return motion lof said piston being accomplished by thespring of the register.

Having thus described my invention, what I claim as new, and desire tosecure byLetters Patent, isu

l. In a paper-makers gage, a number of parallel rollers, sliding boxesfor said rollers, a frame on which said boxes are mounted, and a headresting on the upper roller, in combination with the horizontal lever E,which is mounted on said frame and connected With said head, thevertical lever F 'vhich is connected at top With said lever E, thehorizontal lever G, which is mounted on said frame, connected with thebottom of said le ver F, and a register connected with said lever G, agovernor intermediate of said register and said lever G, and connectedtherewith, and a universal joint supporting said governor, substantiallyas described.

2. In a paper-makers gage, a number of parallel rollers sliding boxesfor said rollers, a frame on which said boxes are mounted, and a headresting on the upper roller, in combination with the horizontal lever E,which is mounted en said frame and connected With said head, thevertical lever F, which is connected at top With said lever E, thehorizontal lever G, which is mounted on said frame, and connected Withthe bottom of said lever F, a duid-receiving cylinder on said frame, apiston With a port in said cylinder, a piston-rod passing through theupper and lower ends of said cylinder and connected at top with thelever G, and a register Whose operating part is connected with thebottom of said pistonrod, substantially as described.

3. In a paper-makers gage, a roller, a sliding journal-box therefor, aregister adapted to be operated by mechanism controlled by said roller,a governor intermediate of said register, and mechanism, and a universaljoint connecting said governor With the frame of the gage, said partsbeing combined substantially as described.

4. In a paper-makers gage, a number of parallel rollers, sliding boxesfor said rollers, a frame in which said boxes are mounted, and a headresting on the upper roller, in combination with the horizontal lever E,which is mounted on said frame and connected with said head, thevertical lever F, which is connected at top With said lever E, thehorizontal lever G, Which is mounted on said frame, and connected withthebottom of said lever F, a iiuid-receiving cylinder on said frame, apiston With a port in said cylinder, a piston-rod passing through theupper and lower ends of said cylinder and connected at top with thelever G, and a universal joint connecting the governor with the supportthereof, substantially as described.
